Which factor affects takeoff, landing, and cruise flight operations due to sudden wind changes?

Wind gusts are sudden, brief increases in wind speed that can dramatically impact the stability and control of a UAS during takeoff, landing, and cruise flight. During takeoff and landing, UAS are often flying at lower altitudes and speeds, making them particularly susceptible to these rapid changes in wind. For instance, a strong gust can push the aircraft off its intended flight path or cause it to lose altitude unexpectedly.

In cruise flight, while the effects of wind gusts are generally less pronounced compared to the critical phases of takeoff and landing, they can still cause turbulence and require adjustments to the flight path or altitude. Thus, understanding and anticipating wind gusts helps pilots maintain greater control over the UAS, ensuring safer flying conditions.

The other factors listed—air pressure changes, temperature inversions, and visibility issues—do influence flight operations, but their effects are not as immediate or drastic as those caused by wind gusts. For instance, air pressure changes can lead to altitude-related adjustments over a longer period, while temperature inversions affect air stability rather than causing sudden movements. Visibility issues impact a pilot's ability to see obstacles or landmarks but do not directly influence the aircraft's takeoff or landing dynamics in the same way that gust
